Abstract (en)
[origin: EP3287423A2] The present invention provides a glass fiber composition, a glass fiber and a composite material therefrom. The glass fiber composition comprises the following components expressed as percentage by weight: 57.1-61.9% SiO 2 , 17.1-21% Al 2 O 3 , 10.1-14.5% MgO, 1.1-4.3% Y 2 O 3 , lower than 6.5% CaO, not greater than 1% Li 2 O+Na 2 O+K 2 O, not greater than 0.75% Li 2 O, lower than 1.8% TiO 2 and 0.05-1.2% Fe 2 O 3 , wherein the combined weight percentage of these components is at least 98% and the range of the weight percentage ratio C1= Al 2 O 3 /SiO 2 is at least 0.285; said composition can significantly increase the glass strength and modulus, effectively reduce the glass crystallization rate, secure a desirable temperature range (”T) for fiber formation and enhance the refinement of molten glass, thus making it particularly suitable for high performance glass fiber production with refractory-lined furnaces.
